Operation Decisive Storm

Operation Decisive Storm (25 March 2015-) was a military intervention launched by Saudi Arabia and carried out by a coalition of several Middle Eastern countries, with support from Pakistan and the United States, with the goal of restoring President Abd Rabbuh Mansur Hadi to power after the extremist Shi'ite Houthis overthrew him in February 2015. Saudi Arabia led the coalition with 150,000 troops and 100 warplanes, and the other states also provided aerial forces. They bombed Yemen to stop the Houthi offensives against the army of Hadi, as Hadi fled the country after a Houthi siege of his temporary capital of Aden and the capture of the Aden Airport by former president Ali Abdullah Saleh's loyalist forces.

Background
The Yemeni Revolution of 2011 made the country of Yemen, unstable since the start of an insurgency by radical Shi'ite Houthis in 2004, even more unstable. The Houthi militias, backed by the loyalists of the former president Ali Abdullah Saleh (overthrown in the revolution), launched offensives against the government of President Abd Rabbuh Mansur Hadi after the coup, and in 2014, the Houthis forced Prime Minister Mohammed Basindawa to resign. For months after September, there was no prime minister, and in February 2015, Hadi was forced to resign after Houthis took over the capital of Sanaa and took the presidential palace. The Revolutionary Committee of Yemen, led by Houthi commander Mohammed Ali al-Houthi, became the new government, although unrecognized by any other country.
